EX188 Container Operations And Lifecycle Practice Question
An administrator needs to run a container named 'web01' using Podman in the background using the image registry.access.redhat.com/ubi8/httpd-24:latest. Which command correctly starts this container in detached mode and maps port 8080 on the host to port 80 in the container?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
podman run -d --name web01 -p 8080:80 registry.access.redhat.com/ubi8/httpd-24:latest
The correct command uses 'podman run -d' for detached mode, '--name web01' to set the name, '-p 8080:80' for port mapping, and the correct image reference.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
podman start -d --name web01 -p 8080:80 registry.access.redhat.com/ubi8/httpd-24:latest
Why it's wrong here
The 'podman start' command is used for existing stopped containers, not for creating and running new containers from an image.
- ✗
podman container create -d --name web01 -p 8080:80 registry.access.redhat.com/ubi8/httpd-24:latest
Why it's wrong here
While 'podman container create' creates a container, it does not start it. To run it immediately, 'podman run' is required.
- ✓
podman run -d --name web01 -p 8080:80 registry.access.redhat.com/ubi8/httpd-24:latest
Why this is correct
This command correctly specifies detached mode, container naming, port forwarding, and the target image.
- ✗
podman run -b --name web01 -p 80:8080 registry.access.redhat.com/ubi8/httpd-24:latest
Why it's wrong here
The flag '-b' is not a valid Podman run flag for detached mode, and the port mapping is inverted.
